Be it known that l, Edema A. Ross, a oi izen of the United States, residing Chicago,

in the county of look andState f Illinois,

have invented a new and useful Improvernent in Headlight-Casings, of the foilowlng is a specification.

My invention relates to improvements in the construction of locomotive headlight casings with View to facilitating the insertion and retention of the tra'hsparent disks or plates.

This manner of replacing a disk has been slow and troublesome, and my object is not only to make the operation of inserting a disk more easy than hitherto, but to provide a construction of disk-retaining ineans which will hold the disk with great security and in a manner to lessen danger of Breakage from jar in thotravel of thelooomotive.

Referring to Fig. l, e is a l notive-hea-dlight easing secured in position on a ioooinotire-boiler jacketfi. The casing is provided on its front 1566 with a hollow frusto-conioal front or extension 6. The outer end of the projection 6 is open, and its outer edge is eX- panded, as shown, to form an annular curved socket '7, providing an inwan'lly-projeoting flange. Secured by rivets 8 to the inner surface of the extension and back of its socket 7 is an annular outwardly-opening seat 9, in

which is confined e cushioning-ring 10, preferably of rubber, against which the transparent disk 1] is adapted to be seated through the open end of the extension. The disk is releasahl retained against the ring 10 by means of a split Wedge-ring 12, preferably of spring metal and half-round in cross-section, the fiat side of which hears against the outer edge potion of-the disk and the s. l and 2 the split ring acts as an annuar which in expanding names the agenist its seat with great seourlty W11 dis breaks, thering 12f rigs. i and maybe contracted and Withdrawn m a {J w i; Q l.
